@barnee I am not able to recreate the bug anymore, I suppose it’s only the first time I loaded, the result above was done by your method, with the renamed folder instead of the zip file.
Ok… my mistake, reinforcing after the battle is allowed. Thinking back to the original game where you had to move everything in combat. Not a bug… IJN moving navy towards south america and getting stuck due to the canal being closed… this is a bug with the Hard AI.
Thanks to two helpful guys, Greg and Aaron, there is now a new version of AACalc with functionality for AA50 and 1942 (or whatever, I’m way out of it.)
